Structural engineers in Wales

Structural engineering, Building Control calculations and surveys for homes, developments and commercial projects across Wales, delivered remotely nationwide with site visits arranged across the country.

Structural engineering across Wales

Wales spans the terraced valley communities of the South Wales coalfield, the Victorian and maritime stock of Cardiff, Newport and Swansea, stone-built farmhouses and chapels across the rural mid and west, and the slate towns of the north around Bangor and Wrexham. Much of the older housing is solid stone or solid brick with shallow foundations and slate roofs, while the coast and the larger towns carry post-war and modern cavity-wall development. Each brings distinct structural questions, from opening up a valleys terrace built into a hillside, to stabilising a rubble-stone gable or extending a period farmhouse where the walls carry load in ways a modern cavity wall does not.

We provide the full structural remit for Welsh projects: Eurocode calculations and drawings for extensions, loft conversions, wall removals and new openings, structural surveys and defect reports, and design for new build and commercial work. Desktop calculations and reports are delivered anywhere in Wales, and where a survey or inspection is needed we arrange attendance across the country, from Cardiff and the South Wales corridor to Aberystwyth, Snowdonia and the north east around Wrexham.

Ground conditions and mining legacy

Welsh geology is dominated by older, harder rock than most of England: Coal Measures sandstones, mudstones and coal seams across the South Wales valleys, Old Red Sandstone through the Brecon Beacons and the borders, and Ordovician and Silurian slates and grits across mid and north Wales. Steep valley sides bring head deposits and colluvium that can creep on a slope, while river floors and the coast carry soft alluvium. The industrial past also leaves made ground, spoil tips and, in the coalfield, potential mine workings and shafts that must be checked before foundations are designed.

We take the ground and its mining history into account rather than assuming a standard depth, specifying strip, trench-fill, raft or piled foundations to suit the bearing stratum and the slope. Where a Coal Authority search or a ground investigation flags workings, tips or unstable ground, we design the foundations to bridge or avoid the risk so the structure stays stable. On steep plots we also consider lateral stability and retaining structure, not just vertical bearing.

How we work with Welsh clients

Most structural work is done from your drawings, photographs and survey information, so being a service-area practice is rarely an obstacle for clients in Wales. We turn desktop calculations and reports around quickly and coordinate with your architect, builder and the local authority Building Control team so the structure and the design agree before work is priced on site. That early coordination matters on tight valley plots where access for materials and plant is limited.

Where a physical inspection is needed, for a survey, a movement assessment or a check of existing structure, we arrange a visit across Wales. Every output is tied to the Eurocodes and Approved Document A and backed by professional indemnity cover, and the same standards let us also support clients elsewhere in the UK.

Questions

Common questions

Do you cover the whole of Wales?

Yes. We provide structural calculations, surveys and design across Wales, from Cardiff, Newport and Swansea to the valleys, mid Wales and the north around Bangor and Wrexham. Desktop work is delivered remotely and site visits are arranged across the country.

Do you need to visit my property in Wales?

Not always. Calculations for extensions, lofts and wall removals are usually prepared from drawings and photos. A visit is arranged where a survey, movement assessment or inspection of existing structure is needed.

Do you allow for mining risk in the valleys?

Yes. In the South Wales coalfield we take account of possible mine workings and spoil, review any Coal Authority search and ground investigation, and design foundations to suit so the structure is not affected by the mining legacy.

Can you provide calculations for Building Control in Wales?

Yes. We prepare Eurocode structural calculations and drawings ready for your local authority Building Control, written to demonstrate compliance with Approved Document A and to be followed on site.
